Abstract

PURPOSE:To extend the packaging area and to shorten the delay time by providing a third package between two packages at the time of constituting one processing unit of these two packages. CONSTITUTION:Connectors 23 and 24 are packaged away from a back-board in positions facing each other on two first and second packages 21 and 22 constituting one processing unit, and connectors 31 and 32 provided in both ends of a third package 3 connecting two packages 21 and 22 are connected between connectors 23 and 24. Packages 21 and 22 transmit and receive signals to and from another processing unit through the back-board 1 to perform the processing, and an interface signal between packages 21 and 22 is directly transmitted and received through the package 3, and the package 3 processes these signals or transmits them to another package. Thus, the packaging area is extended, and the delay time of signals is shortened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an information processing device consisting of a plurality of packages, and in particular to an information processing device that improves connections between packages when a processing unit includes two packages. Regarding.

[Prior Art] Conventionally, in this type of information processing device, in order to connect signals between multiple packages, a connector provided on the package is inserted into a connector on a board called a backboard on which multiple packages can be mounted. The backboard was wired in such a way that the signals of the multiple packages mounted were connected to other packages at designated mounting positions. Furthermore, if the connector on the backboard side is insufficient to connect signal lines, the packages are connected using a cable provided with a connector at a distance from the backboard.

[Problem to be Solved] The conventional information processing device described above has a CPU,! Regardless of the processing unit, such as a 0-board, it is connected using a backboard or cable, so if one processing unit spans two packages, the processing Interface signals between units are also required, and the number of input/output signals for the package becomes extremely large.As a result, the number of input input signal lines for the package exceeds the limit, and it becomes necessary to reduce the interface by reducing the data width. This may lead to a decrease in performance.

The present invention was conceived in view of the above-mentioned problems.
- When one processing unit spans two packages and many signals are required, such as interface signals with other intermediate processing units or interface signals between processing units, processing such as reducing the data width can be performed. The purpose is to provide information processing equipment that is not required.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pair of packages in which a plurality of packages are mounted on a connector on a common board and operated, in which the two packages constitute one processing medium. Each package is provided with a connector at a position facing away from the common board, and connectors provided at both ends of a third package that connects the two packages are connected between these connectors. It is.

[Example] Is this book 3? An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows one embodiment of the present invention, and is a top view of the backboard and pancage. 1 is a backboard (common board), and a plurality of connectors for mounting packages are mounted on the backboard 1, including connectors 11 and 12 in the figure.

21.22 are first and second puff cages each having a connector 25.26 at each end;
are mounted on connectors 11 and 12 on backboard 1, and these two boards constitute one processing unit. In addition, connectors 23 and 24 are mounted on the first and second packages 21 and 22 at positions away from the backboard 1 and facing each other.

3 in the figure is a third package with connectors 31.
32, and the first and second packages 21.
22 connectors 23.24 and connectors 31.32.
It is implemented by connecting.

This package 3 is also equipped with a processing circuit as in the normal package, and is designed to process interface signals between the puff cages 21 and 22.

That is, the first and second packages 21.22 exchange signals with other processing units via the backboard 1 to perform processing, and the interface signals between the first and second packages 21.22 are as follows: The signals are exchanged directly through the package 3 without going through the backboard 1, and the package 3 processes or transmits these signals to the other package.

Note that, as mentioned above, the package 21.
The interface signal between 22 and 22 can be used as an interface with the backboard board 1, and the cable can be used as an interface with other processing intermediates. Furthermore, by performing processing in the package 3 within a processing unit, the mounting area can be expanded and the delay time can be shortened compared to the case where the processing is performed via a backboard or cable.

[Effects of the Invention] As explained above, in the present invention, when one processing unit is composed of two packages, by providing a third package between these two packages, the processing unit can be Interface signals when spanning two boards can be directly exchanged between packages via a third package without going through a bank board or cable, and even if the processing unit spans two boards, the signal line between the package and backboard can be It can be used as an interface signal between units, and by making it possible to mount components on the third package L, it is possible to expand the mounting area, and the signal delay time can be reduced by simply passing through the connector. This has the advantage that the value can be smaller than when using a backboard or cable.
